It’s no secret cybersecutiy is a growing concern for businesses and individuals, as hackers continue to find new weaknesses and vulnerabilities and exploit them.
One such vulnerability was recently found in log4j, an open-source logging framework that man Java-based applications used to produce debug messages. The vulnerability allows attackers with access to the same network as the application using log4j (such as your home or office) to remotely execute code on the system running the vulnerable application with administrator privelages.
This blog post will discuss what this means for you, how it can be fixed, and how to protect yourself from malicious attacks.
How does this vulnerability affect me?
If you use a Java-based application that uses logfile, there is a chance your system could be impacted by this vulnerability. The first step to mitigating the risk should always be assessing and understanding what’s possible with any given cybersecutiy threat.
What does an attacker need?
– Access to the same network as my computer (i.e., a malicious hacker on your local Wi-Fi or the same Guest Wi-Fi at Starbucks)
– Ability to execute remote code (the default security settings in most systems allow this)
As such, these are likely not risks for end users who take simple precautions like locking down their home/office wireless networks with WPA passwords & changing defaults where available. This may not apply if you’re running applications from questionable sources via side loading apps or websites.
What are some ways I can protect myself against an attack?
The best way you can mitigate this threat is by ensuring your Java libraries are up-to-date, which ensures you’re not using older versions of software containing known vulnerabilities. However, if you’re unable to update your applications or libraries for whatever reason, there’s a list of compatible versions that have been patched against this vulnerability. Plus, Datto Inc. has developed a free tool for MSP’s, as well as a community script, log4shell-tool, available to the public via Github.com, that quickly scans all managed devices and detects log vulnerabilities like Logjam. As a Datto Partner, 1st Rate I.T. Services has complete access to the suite of tools that have been released to aide in mitigating and deterring log4j attacks.
